All scales do contribute in different proportions to the scoring of both PCS and MCS measures. Component analyses showed that there are two distinct concepts measured by the SF-36: a physical dimension, represented by the Physical Component Summary (PCS), and a mental dimension, represented by the Mental Component Summary (MCS). The SF-36 measures eight scales: physical functioning (PF), role physical (RP), bodily pain (BP), general health (GH), vitality (VT), social functioning (SF), role emotional (RE), and mental health (MH). A PubMed search using the term “SF-36 health survey” found 9722 items.
The 36-Item Short Form Health Survey questionnaire (SF-36) 3 is a very popular instrument for evaluating Health-Related Quality of Life. These organizations offer their licensing programs for both scholarly research and commercial applications that evaluate completeness of data, consistent responses and internal consistency, and assure the accuracy of data scoring and proper interpretation as well. The Medical Outcomes Trust, Health Assessment Lab, QualityMetric Incorporated, and Optum Incorporated, the organizations that hold all SF-36 copyrights and trademarks, have developed common policies for granting permissions for the use of SF-36 form. 1 Research tools that have been developed, validated, and patented by enterprises or by the academy must be used according to the specifications of their developers. Access to knowledge no longer belongs to the public sphere but to the private one. Academic organizations work with enterprises and industries to increase the commercialization of scientific research and methods. In the era of globalization, researchers play an important role in the “industrialization” of academy and “collegialization” of research. Researchers should be aware of this procedure and of its possible impacts upon human health. We concluded that the “SF-36 Total/Global/Overall Score” has been increasingly reported in the scientific literature. Overall, 129 (75.0%) out of the 172 studies did not specify the method for calculating the “SF-36 Total Score” 13 studies did not specify their methods but referred to the SF-36 developers’ studies or others and 30 articles used different strategies for calculating such score, the most frequent being arithmetic averaging of the eight SF-36 domains scores. We found 172 articles published between 19 110 (64.0%) of them were published from 2010 onwards 30.0% appeared in journals with Impact Factor 3.00 or greater. We performed searches in PubMed, Web of Science, SCOPUS, BVS, and Cochrane Library databases for articles using such scores. The Preferred Reporting Items for Systematic Reviews and Meta-Analyses method was adapted to a scoping review. This study aimed to evaluate the frequency and to describe some characteristics of articles reporting the SF-36 Total/Global/Overall Score in the scientific literature. However, studies keep on reporting such measure. According to the 36-Item Short Form Health Survey questionnaire developers, a global measure of health-related quality of life such as the “SF-36 Total/Global/Overall Score” cannot be generated from the questionnaire.
